Transistor

Question

n-p-n transistor is connected in common emitter configuration (see figure)in which collector voltage drop across load resistance (800 $Ω$ ) connected to the collector circuit is 0.8 V. The collector current is

Easy

A

0.2 mA
B

2 mA
C

0.1 mA
D

1 mA

Solution

Voltage drop across load resistance,
$\begin{array}{l} V_{L} = I_{C} R_{C} \\ 0.8 = I_{C} \times 800 \\ I_{C} = 1 mA \end{array}$
